You respond to violence with a magically charged expression of disappointment, contempt, or wounded trust.

The triggering creature must make a Wisdom saving throw.

On a failed save, it takes 4d8 Psychic damage and becomes emotionally unsettled until the end of its next turn.

While unsettled:

• It can't make Opportunity Attacks.
• Its attack rolls against creatures other than you are made with Disadvantage.
• If it attacks you, it takes Psychic damage equal to your spellcasting ability modifier immediately after the attack resolves.

On a successful save, the creature takes half as much damage and suffers no other effects.
